Abstract
The invention concerns an artificial sphincter comprised of a strip to be wrapped around the intestine, conduit, tube of the wearer's body, or the like. The strip carries either a single inflatable chamber that extends along its length, or parallel longitudinally extending chambers, or rows of separate chambers, wherein the chambers in adjacent rows are staggered longitudinally along the strip. Passages communicate among the chambers to maintain uniform pressure. A tube communicates into the chambers for selectively delivering fluid to inflate them or to permit them to be deflated. At least one wall of the chamber is flexible and elastic, and that wall faces in around the intestine, or the like, so that upon inflation of the chambers, the intestine, conduit, tube or the like is compressed and occluded. In a variant, the chambers are shaped to have a smaller cross-section toward one longitudinal edge of the strip and a larger cross-section toward the other longitudinal edge thereof.
